What methods can be used to determine the amount of disk space occupied on a server?

To determine the amount of disk space occupied on a server, several methods can be used:

• The df command — shows free and used space on file systems.

df -h

- The `du` command — estimates the size of specific directories and files.
  ```bash
du -sh /path/to/directory

• Monitoring utilities, such as ncdu — an interactive disk usage viewer.
• In systems with a graphical interface, built-in disk analysis tools can be used.

These methods allow quickly understanding which folders occupy a lot of space and how much free space remains on the server.
